Rover by AcademyJS

Rover is a command-line tool for learning programming interactively.

As a developer, you'll work on your machine, execute commands on your terminal, and even write code using your favorite editor. You won't use online editors and compilers (depending on your role, of course). So why would you want to practice coding on your browser?

Rover is a step backwards compared to other popular browser-based learning platforms. But hear us out... As a learner, you need to build experience with setting up development environments, fixing bugs, and other such scenarios which you will encounter on a daily basis. Unfortunately, learning on a browser does not simulate this. This is where Rover shines!

Installation

We recommend you to install Rover through npm, which comes with Node.js when you install it.

Once you have npm installed on your system, you can install Rover:

npm install --global @academyjs/rover

You can check if Rover installed correctly by running:

rover --version

Example

Rover comes with many exercises. For demonstration, we'll solve the Hello World exercise.

To pass the Hello World program, you need to solve the following requirements:

• Write the program in 'hello.js'
• Print 'Hello, world!\n' to the standard output stream

So let's create a file called hello.js with the following content:

console.log("Hello, world!");

For this demonstration, we will save the file on our Desktop. So the absolute path for Ubuntu users is ~/Desktop/hello.js.

Open your terminal and change the current working directory to ~/Desktop like this:

cd ~/Desktop

Every exercise in Rover is identified by a handle. A handle is a unique name given to an exercise. For example, "node/hello-world" is the handle for the Hello World exercise.

You can now submit your solution by running:

rover submit node/hello-world

The output of the command is shown below:

rover 0.1.13 (https://academyjs.com/rover)

    ‣ node/hello-world

      ↪ Print a text message on the console.

        ✔ Write the program in 'hello.js'

        ✔ Print 'Hello, world!\n' to the standard output stream (92ms)

  2 passing (97ms)

Don't worry if the output has a few differences. That's because Rover is updated frequently. So small changes in the output are bound to happen.
